André-Marie Ampère

André-Marie Ampère is an important visionary of the past. Not unlike Newton and Lord Kelvin, Ampère influenced many different fields of science and natural philosophy. In the late 18 th and early 19 th centuries, most of the significant scientific advances came from Italy, France, and modern-day Germany. Ampère’s story is marked with tragedy along with professional achievement.

swiftly learn things and quickly develop his own methods and theories in mathematics and science. By the age of 13, he had read the whole Encyclopedia. While still only 13 years old, he submitted a paper on mathematics to the Académie de Lyon, never having them accepted or published. As a wealthy merchant, his father assumed the role of ‘Justice of the Peace,’ essentially maintaining the local government. In July 1789, many French citizens mobbed together in revolution to attack a military post, the Bastille , formally beginning the French Revolution.

Much of the family’s wealth was seized. The homes they had were lost, and the family retreated to the house his mother grew up in about six miles outside Lyon in a town named Polémieux.

His father kept an extensive personal library, and he encouraged his son to study everything. In Ampère ’s own words, his father ‘knew how to inspire in him a desire to know.’ As a child, his favorite book was ‘Buffon’s Natural History,’ but he also studied Euler, Newton, Rousseau, and more.
